Question

The cooling in refrigerator is due to:

• A. reaction of the refrigerator gas
• B. expansion of ice
• C. the expansion of the gas in the refrigerator
• D. the work of the compressor

Answer 1

The correct option is C the expansion of the gas in the refrigerator

The cooling in refrigerator is due to the expansion of the gas in the refrigerator. The compressor compresses the refrigerant vapor, increases its pressure, and pushes it into the coils on the outside of the refrigerator. The hot gas in the coils meets the cooler air temperature of the kitchen, it condenses. The refrigerant absorbs the heat inside the fridge, cools the air.
